Application filed October 14, 1911. Serial No. 654,650.

To all whom, it may ionamin Be it known that I, lVlLmau lil. Asume soN,a citizen ot' the United States ol America, residing in the city ot' St.Louis and State of Missouri` have invented certain new and usefullmprovenuuts in Vehiele- Tires, of which the following is aspeeilication.

This invention relates to pneumatic tires. and has for its primaryobjectto provide an improved construction, combination and arrangement ofparts in devices ot' this chan acter whereby they may be simply, andecol nomically constructed Iand rendered durable and ellicient inservice.

More speeitieally, one of the objects ot this invention is to provide animproved pneumatic tire constrtwtion which will he absolutely punctureproof.

Another object is to provide improved means lI'or mounting the tire uponthe rim of thc wheel.

Another objectA is to provide an improved tire tread constructed o'tremovable portions, said portions being providedavith means for.rendering them puneture-prool.

Other and further objects will appear in the specification and bespecilically pointed out in the appended claims` reference being had tothe accompanying drawings exemplityingl the invention. and in which,

Figure l is a side elevation ot a portion otl a wheel provided with myimproved tire. Fig. 2 is a plan view oi the same. parts being shown insection. Fig. 3 is a section on the line lll-HL Fig. l. `Fig'. 4, is aperspetnfve view olf one ot' the tread portions of the tire. Fig 5 is aperspective view oi one of my improved tread supports. Fig. (i is aperspective view of a tread socket detached. Fig. 7 is a section on theline VII-- VII, Fig. 2l. Fig. t4 is a vtragmentary per spective ot' theriln tire seat band, parts be' ing shown itt section. Vl `ig. t) is asection ou the line IKW-1X, Fig. S.

Referring more particularly to the drawings which represent theadaptation ol' my invention to an automobile wheel, the telly l ot saidwheel is provided with a rim band 2, the lateral edges ol which arelormed into hook shaped lla nges 3. rThe tire proper com-- prises anouter shell o'll peculiar construction tO be hereinafter described, aninner pneu matie tube il, and an intermediate cushion 5 otE any suitablerelatively inexpensive material, such as fanvas or the like.

A valve tube t, with its flanged head 7 within the inner tube Lt,extends inwardly through the telly 1 of the wheel, and is threadedexteriorly for the reception of the threaded washer 8 which bears uponthe outer periphery of the rim 2, and for the reception ot the nutI t)which retains the valve tube t3 in position. One or more of the valvetubes t3 may be used, as desired.

llxtending around the rim band 2 is an interlocking bridging strap l0provided with lateral flanges 11 and a'central flange 12, said lateralflanges. when the parts ar* assembled, being in abutment against the rimband 2. and thc central flange being recessed aty lil (see Fig. Si) forthe reception ot' a threaded 'asheln The interlining cushion 5 ispreferably torined with wedge-shaped overlappingl edges. as shown inliig. il. adapting them to be drawn snuglyr together between th-ebridging strap l() and the inner tube `l when inflated.

Referring more especially to Figs. l, 2, 3, 5 and 7, the composite treadembodied in my improved tire comprises a plurality ot' transverselyarranged tread supports orstraps 14 provided with apertures 15 at eachend, adapting them to be articulately connected with the hooked flanges3 of the rim band 2 by means of imperl'orate metallic shields, eachcomprising a series ot metallic plates lt which are articulatelyconnected together to provide a substantially continuous curved surface,by having integrally formed portions 17 ofl'set to provide pintles aboutwhich the bearing lugs 1S ot' adjoining sections are bent to formhinges. The sections nearest the rim hand Q are provided with hook:shaped lianges 1t) which are interlocked with the flanges 3 o't' theband .2 when the interlm-,king bridging strap l() is drawn down into theposition shown in Fig. 3.

As shown 'best in Fig. 5, the flatportion ot the strap lll isV providedwith a series ot rectangular openings 20 for the reception ot' resilienttread units, each of which comprises an inner locking flange Q1. a neck22 litting thealwrture Q0, and an outer head Q3.

iVhen the parts are assembled in ruiming order, the heads 23 tit snuglytogether around thefperiphery of the tire to provide a continuous solidrubber tread surface, as shown in Figs. l and 2.

Extending along the rear edge of each ot the stra is lll, is auelongated rib or lue 24- 16, the metallic box sockets 2G, and the straps14, constitute a complete metal easing which is substantially inpenetrable.

As represented in F 3, S and 9, the in! terlocking bridging band 10 isparted transversely at the valve tube (S. Uien it is desired to removeor dismantle the tire the nut 9 is removed and the tube (3 forcedoutwardly to raise the adjoining ends of the bridging strap l0 into theposition shown in dotted lines in Fig. 9, in ivhich position the lateraledges of said bridge are moved out of abutment with the innermostsections 1G which are hooked to the flanges 3 of the rim ,2. The outershell is then readily removed.

Obviously, various modifications in the details of the embodiment of myinvention, as described herein, can be made without dcparting from thebroad spirit of my invention.

that I claim is:

l. A pneumatic `tire provided with laterally abutting straps extendingaround the periphery of said tire, said straps having apertures therein,resilient tread units mounted yin said apertures and provided withtlanges on both sides ot said straps, the outside flanges being in closeabutment throughout the periphery ot the wheel, and metallic socketsincasing the inner tlanges,

Incasing the locking' said sockets being in abutment throughout theperiphery of the wheel, and in interlocking abutment with shouldersformed on said straps to support said inner flanges. l

2. A pneumatic tire provided with an impenetrable tread comprising aplurality of straps arranged in lateral abutment throughout theperiphery of the tire and provided with apertures, each of said strapsbeing provided with a raised lug'along its rear edge, and resilienttread units mounted in said apertures and provided with recesses fittingsaid lugs,said tread units being thereby supported against peripheraldisplacement.

A pneumatic tire provided with an impenetrable tread comprising aplurality of metallic sockets mounted on and closely arrangedtransversely around the outer periphery ot said tire, a plurality ofstraps arranged transversely of said tire adjacent said metallicsockets, the side edges of said straps abutting each other, openingsformed in said straps, said openings being adjacent a like number ofmetallic sockets, a plurality of resilient tread units mounted in saidopenings, each of said tread units having an inne and an outer head,said inner heads being seated in said metallic sockets, said outer headsresting on the periphery of said straps forming a tread, and said innerheads forming locking flanges.

4. A pneumatic tire provided with an impenetrable tread comprising aplurality of straps arranged transversely of the tire, and' providedwith apertures,resilient tread units mounted in said apertures andprovided with flanges interlocking beneath said straps, and metallicsockets incasing said fianges and interlocking with said'straps, saidsockets heilig in abutment transversely and longitudinally of the tireto provide an impenetrable shield.
